Shell Script To converts letters to uppercase
Hello, I'm new in linux, please help me to write this shell script and explain them
1- Write a shell script (trans.sh) that : - Take as command-line options any number of text files -Read in each of these files, converts all the letters to uppercase, and then stores the results in a file of the same name but with a .caps extension 2- Write a script (execadd.sh) that will take a single filename as an argument and adds execute permission to the file for the user, but only if the file is a regular file. Your script must check to see that there is exactly one argument. If there are no arguments or more than one arguments, your script must produce a "usage" message that tells how to use the script.

No one is going to complete your school work; I suggest you post whatever work (code) you've done and describe the problem ; so that others can provide the help.
tr command can be used to solve first problem : Shell Script To Translate All Characters In a File To Lowercase Use if command and test command to see if file executable or not ... Code:
usage(){
echo "Usage: $0 filenane"
}
file=$1
[ $# -eq 0 ] && usage
if [ ! -x $file ]
then
chmod +x $file
fi
